IRRIGATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 778,323, dated December2'7, 1904.

' Application filed August 5, 1903. Serial No. 168,380.

To aZZ whom it may concern:

. the water is conveyed by means of subterranean pipes to such pointswhere the same is to be used, at which points the water is caused toflow out of upright branches projecting to the surface of the ground andin communication at their lower ends with the pipes, and I have providedsuch means as will enable its use on ground whose surface is unevensuch, for instance, as on side-hills. I accomplish this by means of theapparatus which is more particularly described and claimed hereinafter.

The accompanying drawing shows a cross-v sectional view of my invention.

The system of irrigation herein shown is separated into differentdivisions, two of which, A and B, are disclosed, the idea being to adaptthe conveying-pipe G F for the supply of a large number of branches EEat the same time,.and this result is obtained by arranging thedischarge-openings of the upright branches in a horizontal line or evenwith each other rather than making each branch of the same length, sothat the discharge-openings will occupy a plane parallel with theconveying-pipe G F. In the latter instance the lowermost branch woulddischarge all the water and the branches above the lowermost woulddischarge a diminishing volume of water, if, indeed, any at all weredischarged. By arranging the branches so that the discharge-openingsthereof are on a horizontal plane with one another or on a levelirrespective of the dip of the ground, the water will flow up and out ofeach branch in equal volume.

The conveying-pipe G F is shown as occupying'a slanting position, asgoing downhill, and at suitable intervals the branch pipes E E E arelocated, the branch pipes being in com- 5 munication with the pipe G Fand projecting by the dotted line.

above the sloping surface of the ground, the branch pipes of eachsection having their discharge openings or ends located on a horizontalplane or level with one another, as disclosed The discharge-openings ofeach section are arranged on parallel planes with one another, aspartially shown in the drawing.

In order to prevent the water flowing out of the discharge-openings fromcutting holes in the ground immediately. surrounding the upright pipes,I provide valved catch-basins H H, which encircle the protruding ends ofthe upright branches and are set into or upon the ground-line parallelwith the conveyingpipe F, the water gently Welling out of thecatch-basins to the ground. A full description of these catch-basins isincorporated in my copending application for patent thereon,

filed April 15, 1903, Serial No. 152,789, and hence further descriptionherein would appear unnecessary.

The upright branches at the ends of the different sections do notconsist of a single pipe, as do the intermediate branches, but are ofdouble size, as shown, and are each provided with a vertically-extendingpartition 1, which virtually forms the trunk branches into two pipes 7and 8, the partition extending into the conveying-pipe G F. That portionof the partition which is in the conduit-pipe G F is provided with anaperture 2 therethrough to permit the passage of water, the remainingportion of the partition constituting a guide and stop for theslide-valve 3, from which a handle 4: extends up through the pipe? to apoint where it-can begrasped and the valve operated. The upper end ofthe partition does not extend to the top of the trunk-pipe; but guides 55 are provided in alinement with the partition, the guides adapted toreceive slats 6 6 therebetween, whereby to build the partition to theheight of the branch pipe, if desired. The purpose of this constructionis to permit more or less of the water which is shot up the branch pipe7 to flow over the partition and down the branch pipe 8. By means ofthis arrangement the flow of water from the branch pipes in each sectioncan be controlled and graduated. If a gentle floW only is desired, theslats 6 6 are removed; but if a large head of Water is needed thepartition is built up by means of the slats, in this Way attaining amost advantageous result.

It is evident that slight changes might be made in the form andarrangement of the several parts described Without departing from thespirit and scope of my invention, and hence I do not Wish to limitmyself to the exact construction herein set forth; but,

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. An irrigating apparatus comprising a conduit-pipe, a plurality ofbranch pipes, trunk branch pipes arranged at intervals, alongitudinally-extending partition located in each trunk-pipe andextending into the conduit-pipe, that portion of the partition Withinthe conduit-pipe being apertured, a slidevalve controlling the aperturein the partition, that portion of the partition Within the conduit-pipeforming a valve-seat for the valve, and means for operating the valve.

2. An irrigating apparatus comprising a conduit-pipe, a plurality ofseries of branch pipes, each series constituting a section, trunk branchpipes located at the end of each section, the trunk-pipes being oflarger size than the branch pipes, a central longitudinallyextendingpartition located in the trunk-pipe, means for opening and closing theconduitpipe at a point substantially in alinement with the partition,the partition being of less height than the trunk-pipe and means forincreasing the height of the partition.

3. -In an irrigating apparatus, the combination with a conduit-pipe andbranch pipes, of a trunk-pipe, a partition extending longitudinally ofthe trunk-pipe and of less height than the trunk-pipe, means for closingthe conduit-pipe at the lower end of the partition, guides located atthe upper end of the partition and slats receivable between the guidesto adjust the height of the partition.

In Witness that I claim the foregoingl have hereunto subscribed my namethis 28th day of July, 1903.
